β-1,3-Glucan recognition protein 3 activates the prophenoloxidase system in response to bacterial infection in Ostrinia furnacalis Guenée.

Pattern recognition receptors (PRRs) are biosensor proteins that bind to non-self pathogen associated molecular patterns (PAMPs). β-1,3-glucan recognition proteins (βGRPs) play an essential role in immune recognition and signaling pathway of insect innate immunity. Here, we report the cloning and characterization of cDNA of OfβGRP3 from Ostrinia furnacalis larvae.

Cloning, expression and characterization of Ostrinia furnacalis serpin1, a regulator of the prophenoloxidase activation system.

Serine protease inhibitors of the serpin superfamily are regulators of proteases involved in a variety of physiological processes including immune responses. In this study, we have isolated a full-length serpin cDNA from Ostrinia furnacalis. The 1188 bp open reading frame encodes a 395-residue protein with a theoretical molecular mass of 43.
